How to add an anemone safely in a reef tank

[smokinreefer]

Not the answer you're looking for, but...
There are no guarantees of a nem not moving.

I have had one/some in my tank for a couple years.

I recently removed one because it began to wander and killed a bunch of ricordeas.

That being said, a nem hosting clowns is a very cool thing.

Coincidently I've got a couple rbtas at the moment that need to be removed soon.
